WebThe runtime complexity of the set.pop () function on a set with n elements is O (1). So, Python’s set.pop () method has constant runtime complexity. It simply removes and returns the first element it encounters. You can see this in the following simple experiment where we run the set method multiple times for an increasing number of set elements. WebThe time complexity of the pop () method is constant O (1). No matter how many elements are in the list, popping an element from a list takes the same time (plus minus constant factors). The reason is that lists are implemented with arrays in cPython. Retrieving an element from an array has constant complexity.

Accessing that element can be done in constant time. There are no elements following so nothing needs to be shifted. list.pop (0) removes the first element. All remaining elements have to be shifted up one step, so that takes O (n) linear time. theory laundry in dryer folded
